thorpej 0414c14b05 Changes to better support XScale, round 1, back-ported from GCC 3.2. The GCC ChangeLog does not have a complete description to quote here, so: arm.c: * arm_override_options(): Set arm_is_scale according to the the -mcpu=xscale option. Set arm_constant_limit to 2 if arm_is_xscale. * arm_adjust_cost(): If arm_is_xscale, account for stalls that can occur due to shifted operands. * arm_gen_load_multiple(): Account for the cost of ldm vs. ldr if arm_is_xscale. * arm_gen_store_multiple(): Likewise for stm vs. str. arm.h: * CONSTANT_ALIGNMENT(): Use a constant alignment factor of 2 if arm_is_xscale. * MOVE_RATIO: Set to 4 if arm_is_xscale. arm.md: * Add XScale scheduling parameters. * Define a "shift" attribute (used by arm_adjust_cost()) and give it to the appropriate operands on andsi_not_shiftsi_si, shiftsi3, shiftsi3_compare0, shiftsi3_compare0_scratch, notsi_shiftsi, notsi_shiftsi_compare0, not_shiftsi_compare0_scratch, abssi2, neg_abssi2, extendsidi2, cmpsi_shiftsi, cmpsi_shiftsi_swp, cmpsi_neg_shiftsi, arith_shiftsi, arith_shiftsi_compare0, arith_shiftsi_compare0_scratch, sub_shiftsi, sub_shiftsi_compare0, sub_shiftsi_compare0_scratch, if_shift_move, if_move_shift, and *if_shift_shift.		2002-08-20 23:46:44 +00:00

HOW TO BUILD A CROSS COMPILER
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[Section to be written.]

See also: http://www.netbsd.org/Documentation/cross/


IMPORTED VERSIONS
~~~~~~~~~~~~~~~~~
The following software is in gnusrc/gnu/dist/toolchain, in a unified build
structure:

    gcc-2.95.3
    binutils-2.11.2
    gdb-5.0


IMPORT STEPS
~~~~~~~~~~~~
1. All distributions were unpacked and all `.cvsignore' files were
   removed.

2. All files in gcc's `include' top level directory were removed from
   binutils's `include' top level directory (these are the libiberty
   include files).

   cd gcc-*/include; for f in *; do rm -f ../../binutils-*/include/$f; done

3. The gcc distribution was imported in one shot into
   gnusrc/gnu/dist/toolchain, including the recursive build structure.

4. The binutils distribution was stripped down to the following directories,
   with no files at the top level:

   bfd, binutils, gas, gprof, include, intl, ld, opcodes

5. Binutils was imported into gnusrc/gnu/dist/toolchain, which included
   only the subdirectories above.

6. The gdb distribution was stripped down to the following directories,
   with no files at the top level:

   gdb, mmalloc, readline, sim

7. Gdb was imported into gnusrc/gnu/dist/toolchain, which included only
   the subdirectories above.
